To all whom it may concern:

Be it known that I,-BEN JAM1N D. CnAM- BERLIN, a citizen of the UnitedStates 1f America, and a resident-of Rochester, New York, have inventedcertain new and useful Improvements in Apparatus for the Manufacture ofBlown-Glass Articles of which the following is a specification.

Inthe manufacture 3f blown glass articles on the blow-pipe the practiceheretofore generally employed has been for a workman to insert theblow-pipe, in the molten glass in the furnace and to manipulate it insuch a manner as to gather thereon suificient glass fora gather, and theblowpipe with the glass has been removed from the furnace and the gathershaped by marvering preparatory to blowing in the mold. This process iscomparatively slow due to the time consumed in eifecting a propergather, and in .marvering.

My present invention has for its object to.

retain the blowing on the blow-pipe with its advantages but to dispensewith the'delays which have attended working in thethis application shownseveral forms'of de-- vices capable of coaction with a form'of blowingmachine shown in my other appli-.-

Fig. 13 is an embodiment of a structure somewhat similar to Fig. 11 butwitha bottom delivery furnace instead of aside delivery furnace.

Fig. 14 is a embodiment of my invention.

Fig. 15 is a view of another form of my exit orifice.

Referring to the form of mechanism fragmental view of another shown inFigs. 1 to 8, the furnace A is supported above the floor of the workroomby a suitable framing A, and is provided with an exit aperture B in itsbottom through which the molten glass may flow in a continuous streamduring the working periods.

A bracket A supported on the framing A has a vertical pintle A locatedbeneath the exit aperture B of the furnace, and upon the pintle ismounted the mechanism for severing the stream of glass and forming itinto blanks of the desired size and shape. The supporting frame for thismechanism comprises a radially extendin arm C and a standard D rigidlyconnecte together to oscillate upon the pintle through a limited are.

A mold E has its trunnion e mounted in slots f in the upper end of armsF fixed to the cross shafts F journaled in the web of the radiallyextending arm, and the shaft is, by mechanism to be hereinafterdescribed,.capable of having angular motion imparted-to it for thepurpose of swinging the mold from the position shown in full lines inFig. '1, in which its mold cavity is uppermost and beneath the exitorifice of the furnace, to the position shown in dotted, lines in saidfigure, in which the mold cavity faces outwardly. In the latter positionthe mold is steadied and held by horizontal faces a on the bifurcatedtop 0 of the arm C, which faces receive rollers e mounted upon the sidesof the mold. The

tilting of the mold in swinging from one position to another is furtherassured by the beveling of the inner end of that face 0 which engagesthe lower roller 0, as is shown at 0 Fig. 1.

Located above the mold is the severing mechanism, comprising a cuttingedge G formed upon the upper end of the standard D and which may becooled or heated asdesired by circulating a proper medium through thecavity 9 in the head of the structure immediately adjacent thereto, andthe blades h, located at diametrically opposites sides of the rotaryknife H, which is also hollow to permit the circulation of temperaturecontrolling medium through it. This knife is mounted upon the horizontalshaft h carriedin the side web 01 of the standard D and is driven by thereciprocating rack I which engages a pirion z" loose upon the shaft butadapted to be clutched therewith for the purpose of driving theshaft inthe cutting direction by means of a pawl and ratchet z". The rack isreciprocated in a direction to cause a cutting motion of the bladeby'means of its articulation to the upper end of a link K pivoted at thebase of the standard D antl is thrown back to its normal position bymeans of a spring 1:. To preventbackward movement of the cutting blade,due to the friction of the parts, a spring 2' may be aflixed to thestandard and bear upon squared or other: wise suitably shaped faces ofthe shaft 71. which will also tend to arrest the knife in the positionshown in Fig. 1, after it has completed its cutting motion. It will benoticed that the knife with its two diametrical cutting edges is soshaped that the descending stream of glass does not contact therewithwhen the knife is in normal position and that in cutting the only pointof contact between the glass and knife is at the cutting edge. This isimportant in preventing the heating of the knife and the impropercooling of the descending glass.

The above constitutes the mechanism by whichthe glass is cut and thesevered gob glass molded in blanks of proper form and the blank moldpositioned horizontally. Such mechanism is especially adapted for use inconnection with a blowing machine of the type shown in my otherapplication Serial No.'551,198 before referred to. In that application,a blowing machine is described adapted to support a plurality ofblow-pipes and to manipulate them in a certain predetermined way. Amongthe manipulations of theblow-pipe which are thus performed are theprojection of the blow-pipe in a substantially horizontal position intoa furnace, the dipping ofthe blow-pipe to effect a gather and itswithdrawal from the furnace, a marvering of the gather and a verticalpositioning of the blow-pipe for elongating and molding. Inas'much asthe gathering and marvering may be no longer essential with the type ofmachine herein shown in which the blank is cast to proper form, suchfunct ons of my prior machine mav be suppressed and the movement bvwhich the blow-p pe is horizontally projected into the furnace mouth insuch prior application be utilized to cause the fixing of the blank tothe blow-pipe. As stated in my prior application the movements of theblow-pipe through a vertical arc are governed by a cam plate so that bya variation in the shaping of such cam. the dipping motion of theblow-pipe and the swinging of the blow-pipe for marvering mav be readilvsuppressed.

I have in Figs. 1 and2 shown, in outline, the machine of mypriorapplication. For the present purpose it is suiiicient to state that themachine comprises a' rotary head plate L carrying a plurality of framesL pivoted thereto, with mechanism for oscillating such frames throughv alimited are around a vertical pivot, wherein" such frames may be causedto assume positions of greater or less inclination in respect to theradii of the traveling head at the extremities ofi which they may bepivoted; blow-pipe supment of the cooperating blow-pipes carried framesand mechanism whereby such supports may be'rotated around a horizontalaxis in respectto such frames, whereby in.

addition to thetranslatory motion of the blow-pipes as a whole aroundthe center of rotation of the head plate, each blow-pipe may bemovedhorizontally through a limited are around the pivotal connection.between its frame L and the head frame and in a limited arc in avertical plane around the connection between its support'and its frameL. 'The blowing mechanism is not shown in these figures as the same isof the construction previously disclosed .and as far as concerns thepresent invention may be modified in any desired way.

For the purpose of coordinating the movements of the blowing machine andof the cutting and molding machine herein de-' scribed in such a waythat the severed and molded blank contained in the casting mold will bestuck upon the end of the blowpipe carried upon the blowing machine, Ihave devised the following mechanism.

As stated the cutting and molding mechanism is mounted to oscillate uponthe pintle A .and is normally at that limit of its movement which isshown in full lines in Fig. 2, that is to say, it is thrown rearwardlyin respect to the translatory movein the blowing 'machine, the directionof movement of which is indicated by the arrow in the same figure, itbeing understood that the blowing machine is fixedly located at suchdistance'f'rom the. center of move-' ment of the cutting and moldingmechanism as will permit the proper. functioning of'the mechanism to behereinafter described.

The parts being in the position, stated ablow-pipe L 'carried by theblowing ma- -chine is, by its movements, brought over i so guides m'formed by a bifurcation" on the top of the arm C, and is lowered intosuch bifurcation, whereby during the period that such engagementsubsists the blowing machine will be connected to the cutting andmolding mechanism. The continued rotation of the rotary head L will movethe pivot of the blow-pipe frame from the position shown in full linesto that shown in-dotted lines in Fig. 2, and in so doing the "frame Lwill swing upon its pivot to assume a radial position in respect to therotary head, and the arm of the severing and molding mechanism will beswung thereby through an arc to assume a position parallel with theblow-pipe. During this movement. due to the fact that the parts areapproaching the line joining the axes of movement of the rotary head andof the severing and molding mechanism, the blow-pipe will be projectedtoward the axis upon which the severing and molding mechanism swings.

Upon the lower. side of each blow-pipe frame L of the blowing machine isplaced a cam M, withwhich an anti-friction roller 01 carried upon theouter end of an arm N upon the end of a shaft 97/ mounted in the.

outer end of the arm C is adapted to run when such frame is projectedtoward the cutting mechanism. -The opposite end of the shaft n= has anoppositely extending arm N which is articulated to one end of a lever Npivated at n in the arm C, the

- opposite end of the lever N being articulated to an arm N fast uponthe moldingand cutting shaft F whereby, when in the movement of'theparts, the blow-pipe carrying frame L approaches the line Joining theaxes of the two elements, the arm N is depressed and through the systemof 'movements before described the mold will be shifted from itsvertical to its horizontal position, being at the same time projected nto pass the highest point m of the cam M, and will permit a slightmovement of the mold to correspond with the continued vslight advance ofthe blow-pipe due to the swing of the latter upon its several pivotalmountings. The severed and formed blank is by this mechanism struck uponthe end of the blow-pipe'and while further movement of the travelingframe past the dotted position of Fig. 2 will cause a recession of theparts andpermit the blow-pipe to with-.

draw the blank fastened thereto out of the mold cavity, it may bedesirable to provide for the rapid removal of the mold away from theblank afiixed as aforesaid to the blow-pipe, in order to prevent thecooling of the blank or the heating of the mold. F or this purpose thearm N is not rigid upon the shaft 41. but is mounted thereon by adiametrical pivot n so that it has a lateral motion. Alateral cam m isfixed in the guide run formed on the cam. M, and the wall of the run iscut away at m whereby at the desired time the end of the arm N isshifted laterally to disengage the roller 7% from the mold tipping camM, whereby the control of the latter over'the former will be destroyedand the mold returned to normal position by the spring n.

For the purpose of" properly positioning the blow-pipe axially inrespect to the mold cavity in the sticking position, a plurality of jawsO are pivoted on the web of the arm 0 around the axis of the blow-pipewhen in such position, the outer ends of such armscarrying anti-frictionrollers, and their inner ends being normally in the path of the moldwhen projected outwardly and being adapted to be struck thereby for thepurpose of causing the forward ends to close upon the blow-pipe when themold is projected outwardly. thereby steadying the blow-pipe.

The severing mechanism is likewise actuated from the blowing machine andthe device for effecting this consists of a rod P having its rearwardend connected with the lever K of the severing mechanism and its forwardend guided in a bearing p adjacent to the blow-pipe receiving slot m.Beyond such bearing 1) the rod P has pivoted thereto a spring-pressedfinger P pressed by a spring P toward the blow-pipe and against anabutment P carried by the arm 1: from the blow-pipe receiving guide Uponthe engagement of the blow-pipe in the guide the end of the finger P isengaged by the end of the blow-pipe support and the movement of thelatter toward the center of rotation of the severing mechanism projectsthe rod P inwardly in the direction of the arrow in Fig. 7, thusactuating the severing mechanism. After a stroke of the rod P,determined by the adjustment of the abutment P the latter will, due tothe motion of the finger P relative thereto, force the latter away fromthe blowpipe and free the finger P from the blowpipe support, thuspermitting the spring k to return the knife-actuating rack I to initialposition.

By the mechanism above described is provided a severing and moldingdevice and a cooperating continuously moving blow-pipesupporting'mechanism with coordinating devices whereby the movement ofthe blowpipe supporting mechanism will actuate the severing and moldingmechanism to sever and mold a charge and to cause movement of thesevering and molding mechanism to accommodate the continuously movingblowpipes, and whereby the molded blank will be stuck upon the end ofthe blow-pipe. After the operations above referred to the blow-pipeswill be lifted out of the guiding bifurcation m into the radial arm ofthe molding mechanism and will be given such movements in the blowingmachine as are necessary for completion of the article, thus releasingthe severing and molding mechanism which may then be returned to itsinitial position by any appropriate device, such as a spring Q.

In order to control the temperature of the issuing stream of glassbefore it islsevered it is desirable to inclose the'same in a shield B?which may be provided with means,

such as the pipe B for introducing heating or cooling media as may bedesired, for in; stance, such as a blast of gaseous fuel.

In Fig. 9 I have shown another form of severing and molding mechanism inwhich 1n lieu of a single mold cavity present in the mold of the reviousstructure, a plurality .of mold cavities are present and the mold isrotated on its horizontal axis through an arc of 90 for presenting afilled cavity to the blow-pipe. In this figure moreover the severingmechanism is provided with means for compressing the glass in the blankmold. The furnace A is of the structure previously described and beneaththe exit, orifice B thereof is an inclined trough R carried upon thestandard D which is mounted on the pintle A Surrounding the standard andrigidly attached thereto is the hub of the radial arm C, the axis of thepintle being as before beneath the exit orifice. Mounted in abifurcation upon the arm C is the shaft of the blank mold E which isshown as provided with four mold cavities, diametrically opposite eachother, the axis of the mold being situated below and in front of thelower lip or end of the trough R and in such position that the uppermold cavity will receive the glass flowing from the latter. Four pins 6are spaced equidistant upon one end of the mold and are adapted to beengaged by a click f mounted upon the free end of a crank arm F pivotedto the mold bracket, and whose oppos1te end is articulated to the leverN so that upon the inward movement of the latter the click will engageone of the pins e and turn the mold through an arc of 90, the click thenfreeing itself from the mold due to the respective centers of movement.The arm N may be actuated by mechanism similar to the mold turningmechanism of Figs. 1 to 8. Pivoted in a projection upon the arm C infront of the mold bracket is the combined cutter and presser H whosetail k is adapted to be engaged by a pawl k carried upon the lever Kwhen the latter is actuated by a rod P to bring the cutter past thefixed knife edge G located beneath the trough. The cutter consists oftwo parts namely the tail portion k which is pivoted in a projectionupon the arm C and the presser and cutter portion b which is pivoted tothe tail portion if, and is spring pressed thereon, so that upon theactuation of the rod P, (which may be effected from the blowing machinein the same manner as the rod P of Figs. 1 to 8 is actuated,) the cutterand presser not only sever the stream flowing from the trough but thepresser k will press the severed glass into the mold cavity, which willthen be turned through an arc of 90 to receive the incoming blow- P p Asa means for permitting regulation of the distribution of the glass atthe cutting point, I prefer to make the trough R adjustable ininclination, this being accomplished by pivotally mounting its forwardend as at 1', and providingan adjusting.

being such that each machine projects its blow-pipe toward the center ofthe severing mechanism in succession, and'the severing mechanism isrotated at such speed as to present a filled mold to the blow-pipe ofeach machine in succession. It will be seen in the construction shown inFig. 10 that as the glass in one mold cavity is being stuck upon theblow-pipe the succeeding mold cavity is being filled. Hence the severingand molding mechanism of this type has a sufliciently rapid rate ofproduction to supply the four blowing machines in suc- .cession. Iprefer, as shown, to cause the rotation of the blowing machines and ofthe severing and molding mechanism upon its axis, by the same motorwhereby a proper coordination of the blowing machines with each otherand with the angular movement of the severing and molded mechanism isobtained, and. to actuate the glass severing mechanism and the moldmoving mechanism fromthe blow-pipe frame of the blow-pipe with which ithas a cooperative relation, as thereby a proper timing of theseessential features is secured. I

In Figs. 11 and 12 the exit orifice Btis located in the side of thefurnace slightly above the bottom thereof and is surrounded by heatingpassages B by which-the temperature in the orifice may be controlled.The wall of the furnace immediately at the end of the orifice isprovided with a concaved face plate 9 against which works a rotaryrecessed combined gate and mold E v mounted on a vertical shaft F andthe latter is given angular movement by the rack I actuated from theblowing machine in the manner before described so that a filled moldcavity will be removed from opposite the exit orifice B of the furnaceand pre-' sented to the incoming blow-pipe, the rotation of the combinedgate and mold cutting the stream of glass at the exit orifice itself.The face plate 9 serves also to scrape from the periphery of the gatemold any glass that may be spread thereon.

In Fig. 13 the structure is the same as that shown in':Figs.- 11 and 12exceptthat the exit orifice. B is. in the bottom" of the fur-. naceinstead of on the side, and the mold gate is mounted on a horizontalinstead of a. vertical axis, and instead through an arc of 90 only, thatis to say,

the blow-pipe: is. inserted in that mold case in the structureof themold'of Fig-.9.

of rotating through an arc of 180 between the loading of each moldcavity and the placing of thecharge therein on the blow-pipe rotate whenthe latter comes horizontalas isthe 1 In all of the several form of. thelnven I tion before described, the severed glass is presented to theblow-pipe by the receptacle in which it is contained immediately aftersevering and hence in all these forms the end of the blank which ,issevered in each operation of the machine is the end of the blank which'receivesthe blow-pipe and this will be naturally the hotter one, and inall of them the opposite end is shaped by contact with the moldcavityand forms the bottom of the article.

. In Fig. 14 I have shown a different type of apparatus. In this figurea knife structure H comprising two diametrical reception cavities, eachhaving a cutting edge 0% adjacent to one side thereof is mounted belowthe exit orifice and is adapted to be intermittently rotated through anarc of 180 by a rack sector I driven by the rod P which may be actuatedif desired in the same manner the rod P is operated in Figs. 1 to 8, therack sector being capable of returning to initial position withoutbackward motionof the cutter structure in the same. manner as is therack I of Fig. 1. The cutting edges h cooperate with the watercooledknife 9 located adjacent to the exit orifice of the furnace, and Iprovide a shield g to prevent the throwing of the contents of thereceptacles as the latter are rotated.

One of the receptacles of such a cutter structure having been filledbythe stream of glass from the furnace, the cutter structure is rotatedthrough an arc of 180 and the glass contained therein is dropped intoa"casting mold E which may be of the construction shown in Figs. 1, 2, 6 8and 9, and by this mold is presented to the blow-pipe. It will be notedthat in this embodiment of my invention the severed glass is invertedend for end so that each blank has that end which was the first severedpresented to the blow-pipe and the end which was last sevby segregatingas it were a part of the contents of the furnace. In Fig. 9 the crosssectional area of the stream flowing down the trough R may be adjusted.by the inclination of the latter and made equal to the cross section ofthe finished blank.

In Figs. 1 and 14 the stream of glass has not the same-cross sectionalarea as the mold and hence the blank may have a different character fromthat formed by the severing of a stream of proper cross section.

In Fig. 15 I have shown another device by which the area of the streammay be controlled, this consisting of a gradual enlarge-v ment of theexit orifice of the furnace whereby the cross sectional area of thestream of glass is increased without increasing the rate of flow fromthe furnace. As shown in this figure, the exit orifice B of restrictedsize connects with a discharge tube 6, of greater area, the junctionbeing effected by a tapering section 12 located immediately at the endof the orifice as I consider it important for the finer grades of workthat the stream of glass be given practically the cross section of theblank before the temperature of the glass has been so far lowered as tocause flow marks. To insure the spreading and formation of a solidstream in Fig. 15 the tube 6 is surrounded by a temperature controllingspace I) provided with means for introducing media into such chamber forthe purpose of lowering the temperature thereof and thus chilling theflowing glass into a stream whose cross section is that of the blank.

In Fig. 14 I have also provided the exit orifice with a tube 6 containedin a temperature controlled space I) but in this figure the orificeproper terminates in a square wall I) so that there is no tendency ofthe glass in passing out of the orifice to flow down the walls of thetube and produce a stream of increased cross section as in Fig. 15. Thetemperature controlled space is, however, in this construction importantin that the exit orifice may be closed from time to time by a suitableplug inserted in the tube and it is necessary that means be provided toheat the tube in order to prevent the freezing of the glass at thatpoint when shut off and to permit it to be readily opened whencongealed.

It is obvious that the form of exit orifice shown in Fig. 15 can ifdesired be used in lieu of that shown in Fig. 1 and that in such casethe blank will be cast from a stream of glass having approximately thesame cross section as the blank.

What I claim is 1. In a machine for the manufacture of blown glassarticles, the combination with a receptacle for molten glass having adischarge orifice, of a constantly traveling blank mold and a constantlytraveling blowpipe, means for positioning the mold to receive thedischarge from the orifice and to register with the blow-pipe, and meansfor causing a relative approaching movement of the mold and blow-pipe inthe-last named position of the mold.
